This page is a translation of the Codex - Tyranids: /tg/ edition into 8th edition. Since the Tyranids are now a decent army this codex is basically useless but still a funny idea if you want to play Tyranids in a more peculiar way.

Psychic powers

Unless stated otherwise, all Tyranid psykers may generate their powers from any of the below Hivemind disciplines.

Hivemind's Control:

  • 1: Dominion
Warp Charge: 5
Through this power, Tyranid organisms are able to extend the range at which they can influence other Tyranid organisms.
Select a freindly Tyranids unit within 36" of the psyker that has the Instinctive Behavious ability. Until the end of your next Psychic phase, that unit ignoires its Instinctive Behaviour ability and automatically passes Morale tests.
  • 2: Catalyst
Warp Charge: 6
Many tyranid psykers are known for their ability to make themselves and other Tyranids seemingly uncognizant of even the most grievous of injuries, allowing them to fight on.
Select a friendly Tyranids unit within 18" of the psyker. Until the start of your next Psychic phase, each time that unit loses a wound, roll a D6; on a 5+, the damage is ignored and the unit does not lose that wound.
  • 3: Onslaught
Warp Charge: 6
The hive mind is capable of giving additional energy to the creatures that comprise its vast "body", allowing them to attack even while sprinting.
Select a friendly Tyranids unit within 18" of the psyker. That unit can shoot this turn (even if it Advanced) without suffering any penalties to its hit rolls for moving and shooting with Heavy weapons, or Advancing and shooting with Assault weapons. In addition, that unit can charge this turn even if it Advanced (though not if it Fell Back).
  • 4: Unstoppable
Warp Charge: 8
A more severe form of the energies put into an organism by Onslaught, this power fills a Tyranid creature with so much psychic power as to become a juggernaut, though the influx of energy is prone to killing the organism afterwards.
Select a friendly Tyranids unit within 24" of the psyker. Until the start of your next Psychic phase the target unit gains a 2+ save against any type of wounds, even mortal wounds and adds 1 to both its attack and strenght charateristic in a turn in which he charged. It may also re-roll failed to-hit rolls in both shooting and close combat. At the start of your next Psychic phase the target must immediately pass a Leadership test or be removed as casualty. If the test is passed, it may not take any actions during any phase, make cover saves, and it's hit automatically in close combat until the start of the next Psychic phase.
  • 5: Fury
Warp Charge: 6
The emotion of anger is like all emotions, a product of chemicals, chemicals that Tyranid psykers can stimulate into being with a thought to grant the benefits that animalistic rage can provide in battle.
Select a friendly Tyranids unit within 12" of the psyker. Until the start of your next Psychic phase the target unit adds 1 to both its attack and strenght charateristic if it charged that turn.
  • 6: One Mind
Warp Charge: 7
Through this power, the Hive Mind is capable of turning even the most rudimentary of combat organisms into a formidable beast of battle as they receive the combat skills assimilated by the hive mind over the course of billions of years.
Select a friendly Tyranids unit within 12" of the psyker. Until the start of your next Psychic phase the target unit and the psyker add 2 to their hit rolls in both shooting and fighting phase.

Hivemind's Malice:

  • 1: The Horror
Warp Charge: 6
Select a unit within 24" that is visible to the psyker. Until the start of your next Psychic phase, that unit must subtract 1 from their hit rolls and Leadership characteristic.
  • 2: Paroxysm
Warp Charge: 5
Choose an enemy unit within 18" of the psyker. Until your next Psychic phase, that unit cannot fight in the Fight phase until all other units that are able to have done so. If the target has an ability that allows it to fight first in the Fight phase, it instead fights as if it didn't have this ability. If both players have units that cannot fight until all other units have done so, then alternate choosing which of those units to fight with, starting with the player whose turn is taking place.
  • 3: Mutagenesis
Warp Charge: 6
Choose an enemy unit within 24" of the psyker. The target unit must pass a thoughness test or suffer a -1 penalty to toughness, strength and attacks.
  • 4: The Shadow Notices
Warp Charge: 7
Select a unit within 24" that is visible to the psyker. Until the start of your next Psychic phase, that unit reduces its leadership by D3. If the target is a Psyker it suffers an additional -1 to its rolls when trying to manifest or deny a psychic power. Finally, if the target has the Demon keyword it has to consider its invulnerable save as one point worse.
  • 5: Optical Overload
Warp Charge: 7
Select a unit within 24" that is visible to the psyker. Until the start of your next Psychic phase, that unit only hits on 6s in both shooting and fight phase.
  • 6: Stand and Die
Warp Charge: 6
Select a unit within 24" that is visible to the psyker. Until the start of your next Psychic phase, that unit can't benefit from cover and has to attack last in the fight phase.

Hivemind's Wrath:

  • 1: Cacophony
Warp Charge: 6
Select a unit within 12" that is visible to the psyker. That unit suffers D6 automatic hits with the profile below:
S AP D Abilities
8 -2 1 This weapon wounds on the leadership of the unit instead of the toughness
  • 2: Psychic Scream
Warp Charge: 5
The nearest enemy unit within 18" suffers D3 mortal wounds. In addition, if that unit is a PSYKER, roll two dice. If the result is higher than their Leadership characteristic, randomly select one of their psychic powers. They can no longer use that psychic power.
  • 3: Alien Voice
Warp Charge: 7
Select a unit within 18" that is visible to the psyker. Both the target and the Psyker must roll a D6 and add the result to their Leadership - if the Psyker gets a higher result, the target takes the difference in mortal wounds as their minds and souls are burnt out from being forcibly put in contact with the hive mind, while the result of a draw causes nothing to happen as the mental energies cancel each other out, but if the target gets a bigger result they manage to avoid forming a connection to the hive mind and the feedback instead afflicts the offending tyranid; the psyker's Synapse range is immediately reduced by 6" until the start of his next Psychic phase. Models without Leadership value cannot be affected by this psychic power.
  • 4: Despair
Warp Charge: 7
Select a unit within 18" that is visible to the psyker. That unit suffers D3 automatic hits with the profile below:
S AP D Abilities
9 -3 2 This weapon wounds on the leadership of the unit instead of the toughness
  • 5: Hunger
Warp Charge: 6
Through this power, the hive mind can force other living beings to experience a portion of the terrible hunger that the gestalt consciousness of the Tyranid race feels every day, a hunger far beyond the ability of lesser organisms to control, forcing them to try and eat their comrades to satiate this horrific desire to satiate an unfathomable hunger.
Select a unit within 24" that is visible to the psyker. Roll an opposed Leadership test against the highest Ld value in the targeted unit, if the target fails, the unit immediately suffers a number of hits equal to the number of models in that unit. These hits are resolved using the unit’s majority Strength (if drawn, use the highest) and AP-. Wounds are allocated by the owning player and armour saves or invulnerable saves if better.
  • 6: Warp Blast
Warp Charge: 7
A blast of pure psychic energy either fired as a beam that can pierce the strongest armor, an orb that can rip apart terminators, or as a pulsating blast that can turn even the Astartes inside out, this is a signature ability of Zoanthropes.
Select a unit within 24" that is visible to the psyker. You can immediately make a single shooting attack against that unit using one of the profiles below as if it was your shooting phase.
Weapon Range Type S AP D Abilities
Warp Blast 24" Assault 2D6 6 -3 1 -
Warp Orb 24" Assault D6 8 -4 D3 -
Warp Lance 24" Assault 1 10 -5 D6 You can reroll all wounds roll if you are attacking a Vehicle or a Building. Treat damage rolls of 1 or 2 made by this weapon as 3 instead.

Tyranid Biomorphs (under translation)

Melee Biomorphs

(re)Designer’s Note: Tyranid Melee weapons come in pairs. For game purposes, each pair is treated as a single Melee weapon. This means that Tyranid models must fight with two pairs of any Tyranid Melee weapons to gain a bonus Attack in close combat for fighting with two weapons. For example, a Hormagaunt armed with a single pair of scything talons does not gain a bonus Attack, but a Ravener with two pairs of scything talons, or a Genestealer with a pair of rending claws and a pair of scything talons, does.

Spore Bomb: Unlike other weapons, Spore Mine Cysts are used during the Movement phase. A Harpy can fire its Spore Mine cysts once in each of its Movement phases. If it does so, it counts as having fired one weapon in its following Shooting phase; however, any other weapons it fires that turn can choose a different target to the Spore Mine cysts. To fire the Spore Mine cysts, the Harpy must be Swooping. After the Harpy has finished moving, center the large blast marker on any one model the Harpy has passed over that turn and roll for scatter (it scatters D6"). Units take a hit for each model that is even partially under the blast marker’s final position, resolved using the appropriate profile below.
Spore Burst: If, when the final position of the first blast marker in the barrage is determined, there are no models (friend or foe) under it, place D3 Spore Mine models of appropriate type anywhere within 3" of the blast template central hole so that they are in unit coherency and not within impassable terrain or 1" of an enemy model (any that cannot be placed are lost). These act as a Spore Mine Cluster for the rest of the game.
* Spore Mine weapons can use a wide variety of different mines, which define weapon's Strength, AP and additional rules.
S AP Additional rules
Frag Mine 4 4 Large Blast, Frag Bombardment
Toxin Mine 1 3 Assault 1, Blast, Poisoned (3+)

Frag Bombardment: If a unit charges a unit hit at least once by a weapon with this special rule during the previous Shooting phase, they do not suffer an initiative penalty for charging through Difficult terrain.
Direct Hit: Acid Mines hit only the model directly under the blast template's central hole. If the blast hits enemy models but the central hole does not, it counts as a miss; place an Acid Spore Cluster as described per the Spore Burst rule.
Aerial Minefield Char Mines blast only hit Swooping Flying Monstrous Creatures and Zooming Flyers, despite them being usually immune to blast weapons, and do not affect any other models.
* Char Mines only roll extra dice for Armour Penetration per Melta special rule if the target appears to be directly under the blast template central hole.

Upgrade Biomorphs

Do note, that this does not affect other rules and weapons that wound on flat dice roll, like Fleshbane or Sniper.
  • Burrowing Limbs: Units composed entirely with models with this upgrade may Deep Strike within 12" from a friendly Trygon, Trygon Prime, or Mawloc tunnel or within 6" from a Ravener brood. If it scatters over friendly model, reduce the scatter distance until it could be placed normally.

These hits are resolved at Strength 3 AP- and have the Poisoned and Ignores Cover special rules.
  • Toxin Sacs: If a model has this Biomorph, its close combat attacks have the Poisoned special rule.

Note that this Attack is resolved separately from a model’s other close combat attacks and uses the appropriate profile below. Also note that a tail Attack is not affected by other Melee weapons, Biomorphs, upgrades or special rules belonging to the owning model, or vice versa. For example, a Hive Tyrant with a Heavy Venom Cannon, a Lash whip and Bonesword, a Prehensile Pincer and Toxin Sacs does not gain an additional Attack for fighting with two close combat weapons, nor does its Prehensile Pincer tail attack have either the Smash or Poisoned special rules.

Mutations

In a unit's profile there is a section called "Mutations", followed by a set of model characteristics. For example: a Termagant is (WS:1/BS:1/S:1/T:1/W:-/I:-/A:-/Ld:1/Sv:-/Psy:-/Syn:-). Each characteristic has an associated cost, indicated by the number after the characteristic. This indicates the cost per model to increase that characteristic. Each characteristic can only be improved once, and characteristics with no associated costs (a dash) cannot be improved.

  • (WS) - Adaptive Motion Analysis: +1 Weapons Skill
  • (BS) - Hyper-Reactive Pupils: +1 Ballistics Skill

Hardened Diamantine Tips: The close combat attacks of a model equipped with the Maw-Claws of Thyrax have the Rending special rule, which triggers on 5+ rather than on 6 with 5s being considered 6s for the purpose of armor penetration and the d3 extra penetration die always being counted as rolling a three 3. If the model has Rending Claws as well, then the Rending effect applies on a 4+ instead with 4s also being considered 6s for the purpose of armor penetration. If the model has Patriarch's claws, then the rending effect applies on a 3+ and the model may count itself as having an additional point of strength for the purposes of armor penetration.
  • The Norn Crown
A model with the Norn Crown adds 6" to its synapse range. Additionally, it gains Psyker (Mastery Level 1) special rule. If it already has the Psyker special rule, its Mastery Level is increased by 1. In addition, the model's invulnerable save is improved by one - if the model does not have an invulnerable save, it gains a 6+ invulnerable save.
  • The Hungering Carapace
A model with the hungering carapace improves its armor save by one step, or if their armor save is already a 2+ (factor this in after mutations), they gain a 6+ FNP save, or improve their existing FNP save by one. The hungering carapace grants the It Will not Die special rule to the model it is given to and the unit it is attached to as the slavering symbiont exudes a healing aura, but its most fearsome ability is its power to consume other living beings. For every six rolled by the model using the Hungering carapace in assault either to hit or wound, place a token on the model, for each token, the model gains an instant death attack resolved at the user's strength score + 2 and at AP2 at initiative 1, for every model slain in this manner, roll a d6, on a 4+ the model regains a wound; if the model already has its full wound count, then its it will not die roll is improved by one step for each model slain in this manner for the remainder of the turn.

Double shot 36" 9 2 Assault 2, Blast, Aetherbane
Salvo 36" 9 2 Assault 3, Aetherbane

Aetherbane: The Psyleech Venom Cannon gains a +1 modifier to Strength against units which contain at least one model with the Daemon, Psyker, Chaos Boons, Psychic Pilot, Brotherhood of Psykers or Brotherhood of Sorcerers special rule or at least one model with equipment listed as a mark of chaos, an icon of chaos, an artifact of chaos, or a chaos reward. Successful invulnerable saves against wounds or penetrating/glancing hits caused by the Psyleech Venom Cannon must be re-rolled. In case of rules clash generated by allowing rerollable saves, such as through the daemon of tzeentch special rule allowing the rerolls of one; the Psyleech venom cannon takes precedence, and still forces successful saves to be rerolled; in case of all failed saves being rerollable, such as through fortune, the two cancel out and the invulnerable save is resolved normally with no rerolls. Invulnerable saves generated by the daemon special rule, psychic powers, chaos boons, a mark of chaos, an icon of chaos, an artifact of chaos, or a chaos reward are reduced by one, with 6++ invulnerable saves being removed.
